I'd actually argue that even more so with JRPGs the overall story is less important than the journey than with other media. Very few actually tell a great overall story.
If people like your characters and the situations they're getting into they will easily overlook that they're just going to some dungeons to restore the magic crystals/gain help from some magical being/get the important item/whatever. Alternatively, if your characters and events suck you better have really good gameplay.
